What makes it work
Unitree A2-W Pro
Wheel Shadow — speed across the field. A heavy-load wheeled paradigm combining an industrial-grade mobile platform with high-efficiency wheel-drive architecture: ~180N·m max joint torque, 100kg standing payload, dual LiDAR perception, wireless vector follow, GPS/4G, hot-swappable dual batteries, and speeds up to 6m/s.
High-Efficiency Wheel-Drive, Heavy Industrial Payload
The Unitree A2-W Pro combines a high-efficiency wheel-drive architecture with heavy payload capacity and agility, suited for industrial inspection, park logistics, emergency rescue and more. It weighs about 52kg with its battery, running on 16 industrial-grade joint motors with crossed roller bearings that deliver approximately 180N·m of max joint torque — enough for a standing load of about 100kg and a continuous walking load of about 25kg (up to approximately 35kg ideally). It runs unloaded for more than 3.5 hours (about 35km) or over 1.5 hours (about 15km) carrying a 25kg load, powered by a dual-slot, dual-battery system that supports hot-swapping without stopping the mission. This is an all-new, high-quality mobile hardware platform with an open architecture, ready to use for rapid development and efficient deployment.
Four Pillars of the A2-W Pro
Speed Across the Field
Mobile Platform, Adaptability, Perception & Power
Industrial-Grade Mobile Platform — Heavy-Load Wheeled Paradigm
The A2-W Pro's high-efficiency wheel-drive architecture combines payload capacity with agility, purpose-built for industrial inspection, park logistics, and emergency rescue deployments.
Superior Adaptability — Complex Environments Handled With Ease
An all-new, high-quality mobile hardware platform with an open architecture, ready to use out of the box for rapid development and more efficient deployment across varied field conditions.
Dual-Sided Perception — Zero Blind Spots, Greater Accuracy
The standard A2-W Pro carries a single LiDAR with an HD camera and front light to detect the environment ahead. The A2-W Pro steps this up to 2 industrial LiDARs (front and rear) for zero-blind-spot coverage.
Hot-Swappable Dual Batteries · Unlimited Runtime
A dual-battery parallel design lets operators swap batteries without stopping the mission — the eternal heart for extreme deployments. A reliable triple power system guarantees stable operation from -20°C to 55°C.
Unitree A2-W Pro — In the Field
Shared Platform Design — A2-W Pro
The A2-W Pro shares its core computing platform and connectivity foundation with the legged A2, re-engineered with a 16-motor wheel-drive chassis for high-speed, heavy-load field deployment.

Common Questions — A2-W Pro
How is the A2-W Pro different from the standard A2-W?
The A2-W Pro adds a second industrial LiDAR (front and rear, vs a single LiDAR on the standard A2-W), an expanded wireless vector follow module, expanded GPS and 4G connectivity, an optional high computing power expansion dock, and a higher ingress protection rating (IP56–IP67 with core components at IP67, vs IP56 on the standard A2-W).
How much payload can the A2-W Pro carry?
The A2-W Pro supports a standing load of about 100kg, and can continuously walk while carrying about 25kg (up to approximately 35kg ideally).
How long does the battery last?
Unloaded, the A2-W Pro runs for more than 3.5 hours (about 35km). Carrying a 25kg load, it runs for more than 1.5 hours (about 15km). The dual-battery system supports hot-swapping without stopping the mission.
Are GPS, 4G and the wireless vector follow module included?
No, not on the standard A2-W Pro — these are optional additions. They are included as standard, expanded features on the A2-W Pro.
